Got a 2001-04 Ford Mustang with a Rattling dashboard? Ford has the fix for you. If it’s coming from the dash area and the air registers are hard to adjust, it’s time to install an upgraded part. The vanes on the old style register detach from the pilot holes in the housing. The new design solves the problem. Ask for part # 3Rz-19893-AB.

Use a small screwdriver to pry out the old register. Then snap the new one in place. Repeat the procedure for all the remaining registers.

Get the BEST auto repair informationAlldatadiy.com and Eautorepair.net are the two best shop manuals—period! Unlike the cheaper Haynes and Chilton manuals that cover multiple year models, leaving the exact information you need to fix your car, these professional manuals cover your exact year, make, model. A subscription includes up-to-date the manufacturer’s technical service bulletins, step-by-step removal and installation instructions, illustrations, wiring diagrams, component locations, torque specifications, fluid types and capacities and maintenance schedules. Plus, they contain full trouble code descriptions and troubleshooting instructions.

Which one should YOU choose? If you’re tracking down a wiring issue, Eautorepair.net is the better choice. Eautorepair.net redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. Alldatadiy.com, on the other hand, uses the factory diagrams. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. However, Alldatadiy.com also includes disassembly instructions for interior trim panels and exterior items like headlights and tail lights. If you need to dig into your doors, dash or console, Alldatadiy.com is the better choice because Eautorepair.net doesn’t any interior or exterior trim or body part removal.
